Definitions

  • This invention relates to fuel compositions for internal combustion engines which normally use low lead or unleaded gasoline.
  • the fuels are further characterized as containing an alcohol.
  • valve seat wear is a function - of engine design, load, speed conditions and operating temperature it is highly desirable that a replacement for lead be employed.
  • the use of a lead replacement for valve seat recession is complicated by the fact that a number of newer vehicles do not require lead additives.
  • a number of fuels on the market contain lower levels of lead and still other fuels are essentially lead-free.
  • alcohol-containing fuels such as gasohol or - fuels containing alcohols used to boost octane rating are also widely marketed. It, therefore, becomes desirable to obtain a gasoline composition containing . a lead replacement which is capable of functioning in a multitude of gasoline based fuels.
  • the metal may be selected from the Group la, Ila, Ilia, Va, lb, lib, Illb, IVb, Vb, Vlb, Vllb, VIII and tin.
  • U.S. Patent 3,182,019 issued to Wilks et al on May 4, 1965, describes lubricating and fuel oils including complexes which contain an alkali or alkaline earth metal carbonate in colloidal form.
  • the use of sodium in lead-free gasoline compositions for inhibiting valve seat recession is suggested in U.S. Patent 3,955,938 to Graham et al, issued on May 11, 1976.
  • the sodium may be incorporated into the fuel in a number of different forms such as sodium derivatives or organic compounds which are soluble, or dispersed in the gasoline.
  • simple sodium salts of an organic acid such as sodium petroleum sulfonate can be utilized although the sodium preferentially is added in the form of a sodium salt of an inorganic acid such as sodium carbonate in a colloidal dispersion in oil.
  • Other convenient forms for introducing sodium into the fuel which are described in U.S. Patent 3,955,938 include various sodium salts of sulfonic acids, sodium salts of saturated and unsaturated carboxylic acids, sodium salts of phospho-sulfurized hydrocarbons such as may be prepared by reacting P 2 s c with petroleum fractions such as bright stock, and sodium salts of phenols and alkylphenols.
  • Various optional additives described by the Graham patent include corrosion inhibitors, rust inhibitors, anti-knock compounds, anti-oxidants, solvent oils, anti-static agents, octane appreciators, e.g. t-butyl acetate, dyes, anti-icing agents, e.g. isopropanol, hexyleneglycol, ashless dispersants, detergents, and the like.
  • the amount of sodium additive included in the fuel is an amount to provide from about 0.5 to 20, preferably 0.5 to 10 lbs. of sodium per 1000 barrels of gasoline (2.86g/1000 liters is 1 lb/1000 bbl) .
  • gasoline compositions can be improved by including certain detergents and dispersants.
  • Johnston et al discloses compositions containing a hydrocarbon-soluble alkali or alkaline earth metal- containing composition and a hydrocarbon-soluble ashless dispersant.
  • the Johnston compositions are useful* for preventing valve seat recession.
  • the present invention further describes a composition comprising: (A) at least one hydrocarbon-soluble or dis- persible alkali metal or alkaline earth metal containing composition,
  • A a hydrocarbon-soluble or di ⁇ persible alkali earth metal or alkaline earth metal containing composition

  • A at least one hydro ⁇ carbon-soluble alkali or alkaline earth metal-containing composition.
  • the presence of such metal-containing compositions in the fuel compositions of the present invention provides the fuel composition with a desirable ability to prevent or minimize valve seat recession in internal combustion engines, particularly when the fuel is an unleaded or low-lead fuel.
  • the choice of the metal does not appear to be particularly critical although alkali metals are preferred, with sodium or potassium being the preferred alkali metals.
  • the metal-containing composition (A) may be alkali metal or alkaline earth metal salts of sulfur acids, carboxylic acids, phenols and phosphorus acids. These salts can be neutral or basic. The former contain an amount of metal cation just sufficient to neutralize the acidic groups present in salt anion; the latter contain an excess of metal cation and are often termed overbased.
